Dwyer Series LLC

Series LLC Conductivity Controller

Series LLCSingle Point or Differential Level Service, Compact Size, Up to 6 ft. (1.82 m) Probes

Control valves, pumps and alarms with the versatile Dwyer Series LLC Conductivity Level Controller. Select the required number of probes for single or dual point level detection. Choose probe lengths in 1-foot increments (up to six feet) to adapt the LLC to your specific applications requirements. The LLC features rugged 1/4-inch (6.3 mm) diameter, stainless steel probes, LED monitoring, surge protection, low voltage sensor and different mounting options.

TO BUILD YOUR LEVEL SWITCH:

Controller:
1. Determine your supply voltage. Select between 120 and 240 VAC.
2. Determine the required sensitivity. Select between 10K Ω and 26K Ω.
3. Determine the socket style. Select between 8-pin octal and DIN mount.

Probes:
4. Determine the required number of probes. Specify quantity of Threaded Mounting Couplings, model LLC-82. (A coupling is required for each probe.)
5. Select probe lengths. Specify model numbers for probes.
